Aneurysms are vascular sacs that can cause dangerous brain hemorrhages if they burst. Treatment should be considered if aneurysms are discovered accidentally. There are various treatment options for the aneurysm.
What is a cerebral artery aneurysma?
A cerebral artery aneurysm is understood to be a sagging of a cerebral artery. These sags usually go unnoticed because they usually do not cause any complaints. If an aneurysm ruptures, subarachnoid hemorrhage occurs. Such bleeding is associated with a very high risk of death, often with severe disabilities.
As the size of the aneurysm increases, it can press on neighboring structures, such as the cranial nerves, causing complaints. In some cases, aneurysms are also discovered accidentally on CT or MRI scans.
Angiography is required to accurately visualize the aneurysm. Either as DSA or CT angiography.
An aneurysm that has already bled should be treated just like an aneurysm that causes discomfort. In the case of accidentally discovered aneurysms, the risks of the aneurysm must be weighed up against those of the treatment. To prevent bleeding or bleeding again, the aneurysm must be cut off from the blood supply. This can be achieved by placing a titanium clip on the neck of the aneurysm using microsurgical technology, thus preventing the connection to the blood vessel system. This method is called clipping.
Another possibility is the so-called coil embolization, an intervention in which the aneurysm is filled with platinum spirals from the inside using a catheter via the inguinal artery. If treatment does not appear to be sensible, the shape and size of the aneurysm must be checked regularly by imaging tests.
